Answer:

50°

Step-by-step explanation:

I am assuming that the shape is a right triangle.

All interior angles of a triangle add up to 180°.

x + 40 + 90 = 180\\\rule{150}{0.5}\\x + 130 = 180\\\\x + 130 - 130 = 180 - 130\\\\\boxed{x = 50}

The missing angle should be 50°.

Hope this helps.

Answer:

\boxed{50 }

Step-by-step explanation:

<h2><em>What is a Triangle?</em></h2>

<em>A triangle is the simplest polygon. It is a two-dimensional shape with three straight sides forming an interior, closed space. It has three interior angles. </em>

<em />

<em>1. Subtract the two known angles from 180° </em>

<em> </em>

<em> </em>

<em> </em>

<em>2. Plug the two angles into the formula and use algebra: </em>

<em />\boxed{a+b+c=180}

3. Subtract

\boxed{180-40 =140}

\boxed{140-90=50}

c=50

<em><u>Therefore, The Answer is 50</u></em>

<em> </em>

A table titled hours spent studying has entries 4, 5, 9, 15, 8, 2, 20, 1, 6, 9, 10, 8, 10, 8, 1, 2.
Sauron [17]
The range is the maximum value minus the minimum value. In this case would be 20 - 1 which is 19.

What is the approximate solution to the equation 3t=29 ? 0.3263 3.0650 3.3672 9.6667
Norma-Jean [14]

Answer:

9.6667

Step-by-step explanation:

3t=29

Divide each side by 3

3t/3 = 29/3

t = 29/3

Three goes into 29  nine times  (3*9 = 27 ) with 2 left over

t =  9 2/3

We know 1/3 = .3 repeating

so 2/3  = .6 repeating


t = 9 .6 repeating

Sedbober [7]

Answer:

See explanation

Step-by-step explanation:

The average rainfall when you add all 10 years of rainfall up and divide by 10 is an average of 59.946 inches of rain each year. The equation for the data is y = -0.53x + 64.45, this means that the rainfall is getting less each year at a -0.53 inches of rain each year.

x = year (2004 would be 4, etc)

sergij07 [2.7K]

Answer:

see explanation

Step-by-step explanation:

The exponents can only be added if the bases are the same

Here one base is 12 and the other is 11

So the rule of addition is not applicable.
